Hello from Bristol UK

I'm a retired motor engineer, latterly an IT specialist, in my 60s. I had a part time job in a road bike repair shop and got up to date with STI and Ergo. I was still in the friction shifter era. I ride about 150 mls a week.
I own 15 bikes, mostly early 90s and older. I usually ride a Raleigh Dyna-Tech and a Falcon late 60s
Also Trek 1400 1989
Giant Peleton
Harry Hall
Gitane with spider web fork ends
Raleigh Road Ace
Peak handbuilt in Derbyshire in the early 70s
My newest is an aluminium with carbon fork and a Campagnolo mix
I need help with the Falcon or maybe it's not.
